PURPOSE Xerostomia can diminish the quality of life, leads to changes in normal chemical composition of saliva and oral microbiata, and increases the risk for opportunistic infections, such as Candida albicans. Various artificial salivas have been considered for patients with xerostomia. However, the knowledge on the antifungal and antiadhesive activity of artificial saliva substitutes is limit...

Polymethyl methacrylate (PMMA) is one of the most widely used materials in prosthetic dentistry. Since it was introduced to dentistry, it has been successfully used in construction of denture bases. Acrylic resins have been successful as denture bases because of their ease of processing, low cost, light weight, and colour matching ability,however, acrylic resin denture base materials are low in...

Objective: The aim of this study was to evaluate the flexural strength denture base materials produced by different methods after repair and effect thermal aging.
 Materials Methods: A total 120 specimens were fabricated conventional, CAD/CAM milled, 3D-printed for in vitro study. Specimens divided into four groups; non-repaired groups (N), repaired (R), non-repaired-aged (N-aged), repaire...

Acrylics are compounds polymerized from monomers of acrylic, metacrylic acid or acrylonitrates. The purpose of this paper is to present the technology and use of acrylics for provisional dentine protection in the practice of dental prosthodontics. For this reason, we followed 120 clinical cases from the everyday clinical practice, divided into 4 groups of 30 patients who needed prosthetic recon...

OBJECTIVE The aim of this study was to assess the in vitro cytotoxicity of acrylic resins of different colors over time. METHODS Specimens were divided into 4 groups (n = 6) according to the color of the acrylic resin (Orto Class, Clássico, Campinas, São Paulo, Brazil): Group 1, clear acrylic resin; Group 2, pink acrylic resin; Group 3, blue acrylic resin; and Group 4, green acrylic resin. Al...

Background Polymethyl methacrylate (PMMA) is widely used for the fabrication of removable prostheses. Recently, zirconium oxide nanoparticles (nano-ZrO2) have been added to improve some properties of PMMA, but their effect on the optical properties and tensile strength are neglected. Objective The aim of this study was to investigate the effect of nano-ZrO2 addition on the translucency and te...
